I have a thread somewhere in this section on cacti...
Lophophora diffusa
Though apperently considered a peyote cactus, there appears to be a lack of ethnobotanical information pointing out any systematic usage. One report of ingestion exists to my knowledge, it verifies the hallucinogenic activity of this species, but claims a Tropane like intoxication. One of two well accepted species within the genus Lophophora. 2/P
Hordenine Pellotine Anhalinine Anhalonidine Isopellotine N-methylmescaline Mescaline O-methylpellotine
Pellotine 65-88% % of total alkaloid content
Mescaline 1.3 % of total alkaloid content
Lophophora williamsii
Many books and articles cover all aspects of this cactus' history, ethnobotany, and chemistry, the most indepth being E.F. Andersons Peyote: The Divine Cactus. This plant is the primary Peyote cactus and the most potent of all known mescaline containing cacti. Many forms of L. williamsii exist, many of which are classified as species themselves, but it is unlikely that they will ever gain recognition as such. L. williamsii is apperently a plant with many variations in growth and flower color, but such variations are not good indicators for taxon re-classification.
Mescaline 30 % of total alkaloid content (1 % dry weight)
Pellotine 17 % of total alkaloid content
Anhalonidine 14 % of total alkaloid content
Glycine 8 % of total alkaloid content
Lophophorine 5 % of total alkaloid content
3-Hydroxy-4,5-dimethoxyphenethylamine 1-5 % of total alkaloid content
Alkaloids found in Lophophora williamsii. Please bear in mind this list only contains 6 of the over sixty Alkaloids known to be present in L. williamsii
The sections of Lophophora Williamsii and Diffusa differ chemically in the composition of their alkaloids. L. Diffusa are a lot closer to each other in this respect and stand out clearly from that of L. Williamsii. L. Williamsii contains around 15-30% of the alkaloid mescaline compared with a maximum concentration of only 1.3% mescaline in L. Diffusa. Along side of this, L. Williamsii contains 14-17% of the toxic alkaloid pellotine, whereas L. Diffusas content of the alkaloid can be as high as 65-88%.
(as you can see its pretty important to make sure yuo get the right Loph or you are gonna have one nasty pellotine experience.
